Timothy is 4 years old. Janet is 3 times as old as Timothy. When Timothy turns 12, how old will Janet be?

Question

How old will Janet be when Timothy turns twelve?

Answer 1

J = 3 * T

T = 4

J = 3 * 4 = 12

Janet's currently 12 years old.

 

12 y.o. in future - 4 y.o. now = 8 years have passed.

 

12 (Janet's current age) + 8 years passing = 20 years old in future.
